Using the American football analogy of a defender apparently behind but to the side of a runner "having the angle" on the runner and making the tackle.
Secondly, the Iron Dome missile may be significantly faster than those of Hamas.
Exactly, but if the trajectory changes due to any factor, or there isn’t enough time, it should miss. How can the early warning system calculate all those factors and intercept 90% of the time? It seems beyond remarkable. Maybe with multiple intercept points and ID missiles fired, I could see 90%. But they only fire 2 interceptors per rocket, correct? There are so many factors that can change the trajectory. Are the intercept points calculated on launch towards apogee, or after apogee? Or both? Is there enough time?
Burn time, wind, weight and time all factor into calculating the intercept. So if you got one wrong, then you would be making the best estimation. All of this has to be done by a computer, unless you have plenty of time. I imagine Israel doesn’t have much time from launch to impact.
